Ionic liquids with a theophyllinate anion

Article abstract of DOI:10.1039/c4nj00463a

Ammonium and piperidinium theophyllinate-based ILs were synthesized and characterized. Physicochemical properties, such as thermal stability, phase transition temperatures, viscosity, density, refractive index, as well as surface activity, feeding deterrence, antifungal activity and also biodegradability were determined. The synthesized theophyllinate-based ILs were surface active compounds. They exhibited insect-feeding deterrent activities. At the same time, the studied salts are also efficient fungicides and potential pesticidal ionic liquids. The obtained data suggest that certain structural modifications may increase their biodegradability in order to provide an environmentally friendly product. the Partner Organisations 2014.
